Patented Sept. 15, 1914.

To all 'whom it may concern Y Be it known that I', FREDERICK C. VARNE, a citizen of the United States of America, residing at Mansiield, in the county of Richland and State of Ohio, have invented cerof attachment for the gangs to the beams so that the gangs may have horizontal pivotal movement relative to and independent p of the beams.

- longitudinal-`sectional view of one of the Further the invention has for its object the provision of means which maintain the` dependently of each other and counteractI the pressure of the soil against the disks so as to assist the operator in holding the gangs f in their proper places.

In the drawings: Figure 1 is a top planl view of the invention, in which the diskV gangs are illustrated in out-throw position; Y

Fig. 2 is a similar view showing the disk gangs in in-throw position; Fig. 3 is a side elevation of Fig. 2, one of the traction wheels being removed;y Fig. 4 is a `fragmentary top plan view in which the yone gang illustrated is in in-throw position and is also shown in dotted line position to illustrate the action of the springs; Fig. 5 is an end elevation partly broken away and in section of one of the disk gangs; Fig. 6 vis a disk gangs; Fig. 7 is a front elevation of one of the yokes of the gangs; Fig. 8 is a top plan v iewof Fig. 7.

The invention includes a central tongue 1 to'which the usual draftappliance 2 is at-- tached, Brackets 3 are attached to the tongue 1 and adjustably support a pair of yokes, sleeves 5, being journaled upon the lower ends of the yokesj Beams 6 are in pivotal connection with the sleeves 5I by means of couplingsy 8 which latter are pivotedat 7 to couplings 9, 'the sleeves 5 having keys 10 lwhich are slidable in key-ways 11 formed in the couplings 9. Rods 12 are connected to' the couplings-9 and to the draft appliance 2 for-which purpose eyes 13 are provided on the couplings 9-to engage with the rods 12, Arms 14 aref secured at one end to the lower ends of thefyokes 4v and at their outer ends are formed to provide bearings for the stub axles of the wheels 15, braces 16 being connected tothe arms 14 and to the yokes 4 in order to sustain thearms 14 in rigid relation to the yokes. are secured to the inner ends of the sleeves'5 by means of U-bolts 18, bars 19 being pivoted at one end to the couplings 1 and being slidably passed through arms 2O that are vrigidly secured to the beams 6. The outer or rear ends of the bars 19 are threaded and extend through the eyes 21 formed in the heads of pivot pins 22 which latter are pivotallyrconnectedto the gang yokes 23 by means of clips 24 as depicted in Fig. 7, nuts 25 being engaged with saidthreaded ends of the bars 19 to secure the latter to the pivot pins 22. The yokes 28 are provided with brackets 26 which are rigidly secured thereto, vwhich brackets have spacedforwardly projecting perforated ears 25 throughthe perforations of which ears pivot bolts 27 are passed. The pivot bolts 27 are also connected to cou- Couplings 17 plings 28 the latter being split and engaged over vthe outer ends of the beams 6. The couplings 28 are adjustably secured to the beams by boltsv29, in order that the pivot boltsr27 may be given varying angular relationship to the surface' of the ground to thereby provide for varying corresponding angular disposition of the gang disks relative to the surface of the ground.v Each yoke has an arm' 30 secured thereto by bolts 81' to which the bar 19 ,ispivotallyand adjustably `attached for the out throw position as shown in Fig. 1. For the in throw position the bar 19 is pivotally and adjustably attached to one end of the yoke 23 as shown in Fig. 2.

The bracket 24 which carries the pivot pin 22 is attached to the end of the bar 30 for out throw position as shown in Fig. 1, butis removed and attached to the end of the yoke 23 for in throw position as shown in Figs. 2 and 7. The lower yoke ends are turned outwardly at 23 and have bearing boxes 32 secured thereto by bolts 33 as shown in Fig. 5.

The disks 33 are mounted on a shaft'34 and are held in spaced relation by sleeves 35, two of which latter are journaled in the bearing boxes 32. A pair of coil springs 36 and 37 encircle each of the bars 19 and abut Aopposite sides of the arms 2O at their inner ends and collars 38 at their respective outer ends, the collars 38 being adjustable on the bar 19. Each gang has an operating handle 39 which handles are adjustably secured to the beams 6 by means of bolts 10 which pass through enlarged heads 41 formed on the handles and through similar heads borne by clips 42 which latter are rigidly aflixed to the beams 6. The contacting faces of the heads are preferably serrated to increase the holding efliciency of the parts upon adjustment and tightening of the bolt 10. The beam lifting mechanism (shown in Figj3) forms the subject matter of an application bearing Serial Number 723,411, filed October 1, 1912 and is fully described in said application.

A hanger -15 is secured to the tongue 1, and has hooked ends which when the beams 6 are movedv up into engagement therewith, sustains same in raised position out of engagement with the ground.

Attention is called to the fact that the springs 36 and 37 are set to abut against the arm 20 under compression to assist the-operator in yieldingly maintaining the beams and gangs in a predetermined lateral position, and to counteract the action of the soil on the disks.

I'Vhat is claimed is 1. In a cultivator, a beam, means to pivotally support the beam, a yoke, a gang of .disks connected to the yoke, means to pivotally connect said yoke to the beam, an arm on the beam, a bar pivotally connected to the beam support and passed through said arm, spring means between the arm and bar to tension the latter, and means to pivotally connect the bar to the yoke.
